Definition: Given a simple high-school level math question, you are required to solve it and provide the final answer. The final answer is always a single number. These questions can range from a variety of topics like simple arithmetic, solving equations, converting a quantity from one unit to another, finding remainders/GCD/LCM, finding probabilities etc. Each question has only one correct answer. This answer can be a positive or negative integer, a fraction or a decimal number. If the answer is a negative number use the hyphen (e.g. -42) symbol for the minus sign. For decimal numbers, do not add extra zeros after the decimal point. For fractional numbers, separate the numerator and denominator using a forward slash (e.g. 3/25).
Input: Let d = -54 + 80. Suppose 4*q - d = 2*i, 6 = 5*q + 3*i - 10. Let c be 4/(-10) - (-27)/q. Solve -c*x = -3*g + 8*g - 15, -3*x = 2*g - 7 for x.
